Precalculus: Polynomial Functions and Models (Video #14) | Math with Professor V

Definition of polynomials, how to determine whether or not a function represents a polynomial. Determining the degree of a polynomial. Introduction to power functions and their end behavior. Finding the real zeros of a polynomial function, their multiplicity, determining whether the graph touches or crosses the x-axis at each x-intercept, determining the maximum number of turning points on a graph, and sketching the graph of a polynomial functions with all relevant characteristics. #polynomials #polynomialfunctions #precalculus #mathtvwithprofessorv #mathvideos #youtubemath #precalculusvideos #math #endbehavior #realzeros #multiplicity #xintercepts #behavioratxaxis #turningpoints #sketchingpolynomials #graphingpolynomials #powerfunctions #algebra #mathhelp #mathprofessor #calculusvideos

Thank you so much, I just started pre-calc online and we have no videos or lectures. Your videos are already really helping me they are very clear and concise and the playlist is perfectly set to follow the standard curriculum. Thank you for putting your time and effort into this. I was scared for pre-calc because I've been told that's where the struggle begins but having these videos here consuls and empowers me to be the best student I can be.

hello professor v, i have been seeing your precalculus course. I planned to finish it, because i think your explanations are very clear

Why cant you be my precalc teacher 😭😭 thank you so much I really understood what this lesson was about. it’s kind of crazy how some teachers don’t explain concepts to students.

Professor V, thanks for a lengthy and deep analysis of Polynomial Functions and Models. Polynomials functions are simple to work with, however factoring them from scratch can be problematic. There is an error in problem 2a, when you multiply by negative one. Please check this problem for this small error.
